Genetic opposites attract when chimpanzees choose a mate

Researchers find that chimpanzees are more likely to reproduce with mates whose genetic makeup most differs from their own. Many animals avoid breeding with parents, siblings and other close relatives, researchers say. But chimps are unusual in that even among virtual strangers they can tell genetically similar mates from more distant ones. Chimps are able to distinguish degrees of genetic similarity among unfamiliar mates many steps removed from them in their family tree. Ref. Source 8j.
